In the prior art, after the vehicle positioning device and the electronic control unit are bound, the electronic control unit has data supporting the vehicle locking function, and stores a handshake check key and a device identifier of the vehicle positioning device.

And in a certain time after the motor vehicle key is powered on, the electronic control unit actively initiates handshake verification, namely sends verification information generated by calculation of the electronic control unit to the vehicle positioning equipment, once the two times of handshake verification fail, the electronic control unit judges that the vehicle positioning equipment is detached or replaced, and the electronic control unit actively locks the vehicle to an idle speed.

Because the handshake check between the electronic control unit and the vehicle positioning equipment is actively initiated by the electronic control unit, if the user writes or replaces the electronic control unit without the vehicle locking function, after the key is powered on, the electronic control unit does not initiate the handshake check, and the user can replace the vehicle positioning equipment so as to avoid being locked and locked.

According to the existing unbinding technology between the electronic control unit and the vehicle positioning equipment, a manufacturer sends an unbinding message to the vehicle positioning equipment through the Internet of things or a mobile phone, the vehicle positioning equipment sends the unbinding message to the electronic control unit, and if the unbinding password in the unbinding message and the equipment identifier of the vehicle positioning equipment are consistent with those stored in the electronic control unit, the electronic control unit executes unbinding, namely, the vehicle locking function is closed.

The messages used in the unbinding process are similar, the binding and unbinding passwords set by the manufacturer are the same, the whole process is extremely easy to monitor and crack, once the messages are cracked, a lawbreaker can send the unbinding passwords to the vehicle positioning equipment to unbind the vehicle positioning equipment and the electronic control unit, and therefore the vehicle can be positioned and locked.
